Appropriate technology and sustainable development elements

Short answer

Appropriate technology is low-cost, small-scale, simple, local and eco-friendly technology suited to the place, popularized by Schumacher. Sustainable development has economic, social, environmental and institutional/cultural pillars; it meets present needs without compromising future generations. AT supports all pillars by being affordable, serving local people and being clean.

What do you mean by appropriate technology? What are the elements for the sustainable development?

Appropriate technology (AT) is technology that suits the local social, economic, cultural, environmental and skill conditions of the place where it is used. It is usually small in scale, low in cost, simple to operate and repair, uses local materials and labour, and does little harm to the environment. The idea was popularised by E. F. Schumacher in Small Is Beautiful ("intermediate technology"). It is not "old" or "low" technology: it is the right technology for the situation.

Examples in Nepal: biogas plants, improved cooking stoves, micro-hydro with peltric sets, solar home systems and solar dryers, ropeways, gravity-fed drinking-water schemes, treadle pumps and the traditional ghatta (water mill) upgraded to an improved water mill.

Elements of sustainable development

Sustainable development means meeting the needs of the present without compromising the ability of future generations to meet theirs (Brundtland Report, 1987). Its main elements (pillars) are:

  1. Economic sustainability: steady growth, employment, equitable income and efficient use of resources.
  2. Social sustainability: equity, health, education, gender and social inclusion, community participation, and good governance.
  3. Environmental sustainability: protecting air, water, soil, forests and biodiversity; using renewable resources within their regeneration rate; limiting waste and emissions.
  4. Institutional / cultural sustainability: strong institutions, laws and respect for local culture and knowledge.

            +--------+--------+
            |  Environmental  |
            +-----------------+

Sustainable development is the overlap of all of these. AT supports each element: it is affordable (economic), serves local people (social) and is clean (environmental).
